When two balls of the same diameter are made of materials of different density and mass,
the ball with the greater mass-density will travel farther if projected with the same amount of force, or at the same initial speed.
What factors affect the distance the ball travels?
The distance a baseball travels depends on two primary factors:
the angle at which the ball leaves the bat, and how fast the ball is hit
.
Does a heavier ball travel further?
The heavy object will feel small changes to its speed (its acceleration is close to zero), while the light object will slow down a lot (its acceleration is a large negative number). In the end,
the heavy object will travel farther
, since it was less affected by air resistance.
How does the type of surface affect how far a ball will roll?
Different surfaces of ramp will change the speed of the ball and therefore also the distance it rolls
. When the ball has rolled off the ramp it will continue to roll on the floor, different surfaces of floor will result in different amounts of friction, changing the speed of the ball, and distance it rolls.
Why does a ball slow down as it travels?
The ball, for instance, will feel the force of gravity pulling it downward, the force of the ground pushing it upward direction it is rolling. Since
the force of friction goes against the direction that the ball is moving
, that is the force that will cause it to slow down.
How does weight affect speed and distance?
Weight affects speed down the ramp (the pull of gravity)
, but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
What is the speed of the ball?
The speed of the falling ball as a function of time is
v = 9.8 (m/s
2
) t
and the distance traveled is d = 1⁄2 9.8 (m/s
2
) t
2
. In one second the ball travels 4.9 m. The velocity of the falling ball as a function of time is v = -9.8 (m/s
2
) t j and its position as a function of time is r = (4.9 m – 1⁄2 9.8 (m/s
2
) t
2
) j.
How does speed affect distance?
The faster an object is moving, the longer the distance it takes to stop
. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. If a vehicle’s speed triples, it needs up to 9X’s the distance to stop.
What is the effect of changing the type mass of the ball on the speed of the ball?
If the same force is applied to two objects,
the object with the smaller mass will change speeds more quickly
. For example if a baseball and a bowling ball are thrown with the same force the baseball will speed up faster.
How does mass affect speed?
Mass does not affect the speed of falling objects
, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time. The horizontal force applied does not affect the downward motion of the bullets — only gravity and friction (air resistance), which is the same for both bullets.
Does a big ball roll faster than a small ball?
There are cases where a larger ball can travel faster than a smaller ball
. However, consider the case where both balls are under the same conditions (same mass, and placed at the same height on the same inclined plane, and assume negligible air resistance), then the smaller ball will travel faster than the larger ball.
Will a heavier or lighter object go faster when kicked?
Answer 1:
Heavy objects fall at the same rate (or speed) as light ones
. The acceleration due to gravity is about 10 m/s
2
everywhere around earth, so all objects experience the same acceleration when they fall.
In what surfaces does the ball roll faster?
Answer. It is because the rough surface is having more friction that the smooth surface. A ball, rolls faster in a
smooth surface
because it is having less or no friction at all to stop it.
How does shape affect distance traveled?
The shape of any object will change how far it flies through the air. This is because
the air pushes on the object and slows it down
. If you’ve ever had the wind in your face, tried walking on a windy day, or tried riding your bike, you’ll know that air pushes against you and slows you down.
How does the height of a ramp affect the speed of a ball?
If a ball is running down a ramp, why is it that when you change the height of the ramp, the ball runs down the ramp faster? A:
If you increase the steepness of the ramp, then you will increase the acceleration of a ball which rolls down the ramp
.
What type of ball can be thrown the farthest?
- 112 Ft 6 In (34.3m) – Forward Basketball Shot. …
- 197 Ft (60.04m) – Hockey. …
- 222 Ft (67.7m) – American Football Throw. …
- 1653 Ft (503.8m) – Golf. …
- 72 Ft 9 in (22.21m) – Shot Put. …
- 222 Ft 7 in (67.88m) – Discus Throw. …
- 259 Ft 6 in (79.13m) – Hammer Throw. …
- 278 Ft 2 in (84.81m) – Javelin.
When you throw a ball does air speed it up or slow it down and why?
When you throw something upwards it loses speed
as it moves further away from the earth, due to the earths gravitational pull. ‘Infinitely’ far from the earth the earths gravitational pull is zero, and ‘thrown’ objects no longer slow down as they move away from the earth.
What controls how fast an object falls?
How fast something falls due to gravity is determined by a number known as the “
acceleration of gravity
“, which is 9.81 m/s^2 at the surface of our Earth. Basically this means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity.
Do Heavier Things roll faster?
After a two sample t-test, we find that
heavier rolling objects have a statistically faster clear time for a given inclined plane in comparison to lighter rolling objects
.
Do heavier cars go faster?
It’s clear that
a lighter car requires less force to accelerate than a heavier one
. With a heavier car of the same power you have to accelerate for longer to cover the same distance so you use more fuel.
Why do heavier objects move faster?
There will be a resultant force which will be proportional to the mass of the object. Hence
an object with greater mass feels greater force than the other one
. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.
What is the speed of the ball when it strikes the ground?
Conclusion: The magnitude of the velocity of the ball is
26.3 m/s
for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.
What is the speed of the ball when it hits the ground?
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or
9.9 m/s
.
What is the speed of the ball when it strikes the wall?
Speed of the ball when it strikes the wall ∣v∣=(28. 3)+(−6. 29) =
28. 99 m/s
.
Does speed increase with distance?
| v = ∆s | ∆t |
|---|
How does speed affect acceleration?
If the speed is increasing, the car has positive acceleration. When the car slows down, the speed decreases
. The decreasing speed is called negative acceleration. In both cases, the car is accelerating, but one acceleration is positive and one is negative.
