Is There Friction At Constant Speed? If an object is moving at a constant speed the force of friction must equal the applied (horizontal) force, and for it to be accelerating or decelerating, the force of friction and the applied force must be unequal. Does constant speed mean no force? If a body is moving
How Long Will It Take A Car To Go From A Complete Stop To 44 Km HR If They Are Accelerating? 44 = 0 + 5 * t so t = 44 / 5 = 8.8 hours (not seconds – thanks to Harry Sharp). How long will it take a car to go from a
How Do You Know If Two Lines Have The Same Velocity? When lines intersect on a velocity-time graph, it means that the two cars have the same velocity. When lines intersect on a position-time graph, it means that the two cars are passing each other. How do you know if two graphs have the same
How Do You Know If Something Is Moving At A Constant Speed? To have a constant velocity, an object must have a constant speed in a constant direction. … If an object is moving at constant velocity, the graph of distance vs. time (x vs. t ) shows the same change in position over each
How Long In S Does It Take To Reach Its Highest Point? It takes 15 seconds to reach the highest point. How long does it take to reach the highest point? It takes about 88 seconds for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and
What Will An Object Moving At A Constant Velocity Do Quizlet? “An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force.”. What would an object moving at a constant velocity do? Motion with
Is Centripetal Acceleration Constant In Uniform Circular Motion? The change in direction is accounted by radial acceleration ( centripetal acceleration ), which is given by following relation: ar=v2r a r = v 2 r . … This means that the centripetal acceleration is not constant, as is the case with uniform circular motion. Is centripetal
What Will Happen If A Spaceship That Is Motionless In Deep Space Is Given A Quick Push? If a spacecraft that seems to be motionless in deep space is given some type of quick push, what will happen? … The spacecraft will not move due to air resistance. The spacecraft will move and will not
When A Charged Particle Enters A Uniform Magnetic Field What Is Its Speed? A proton enters a uniform magnetic field of 1.0 × 10 −4 T 1.0 × 10 −4 T with a speed of. 5 × 10 5 m/s . What is the speed of the particle when it enters the magnetic field region?
Which Component Of Projectile Is Constant? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its
