You have more momentum , because you a the bike are travelling at the same speed, but you have much more mass. You therefore have more inertia, and require much more force than the bike to come to a stop. 4.
Which has greater momentum a truck that is traveling with a constant speed or a bicycle that is at rest?
Explanation: Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum. The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.
Does greater momentum move?
An object with mass will have momentum. ... The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.
Which has a greater momentum a large stationary truck or a moving skateboard?
The greater the force acting on an object, the greater its change in velocity, and hence, the greater its change in momentum. A truck rolling down a hill has more momentum than a roller skate with the same speed. But if the truck is at rest and the roller skate moves, then the skate has more momentum.
How is it possible for both a bicycle and a truck to have the same momentum?
For a truck and a bike to have the same momentum, the mass of the vehicle times the velocity of the vehicle must be the same for both of them . Therefore, the lighter, less massive bike will have a much higher velocity than the truck.
What factors does momentum depend on?
Momentum depends upon the variables mass and velocity . In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity.
Which has more momentum a heavy truck moving at 30 km/h or a light truck moving at the same speed?
Which has more momentum, a heavy truck moving at 30 km/h or a light truck moving at 30 km/h? ... both has the same momentum D. cannot be determined .
Does a bullet have more momentum than a moving ship?
So yes , a tiny thing like a bullet can have the momentum of almost anything in size up to a modern cargo ship. The huge ship moves at less than 50 mph, the bullet would have to be propelled at millions of times that velocity to have the same momentum as the ship.
Which has the greater momentum when moving which has the greater momentum when moving?
The more momentum a moving object has, the harder it is to stop. The mass of an object affects the amount of momentum the object has. For example, you can catch a baseball moving at 20 m/s, but you cannot stop a car moving at the same speed. The car has more momentum because it has a greater mass.
Does momentum have direction?
Momentum is a vector quantity; i.e., it has both magnitude and direction .
What happens when two objects with the same mass collide?
When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions . Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.
How does Dr Hewitt break the piece of wood?
How does Dr. Hewitt break the piece of wood? He causes a change in momentum of his hand over a short period of time . ... Increase the change in momentum, and decrease the time duration.
Can a small light ball have the same momentum as a large heavy ball?
5) A heavy object and a light object have the same momentum. ... Reasoning: Momentum = mass x velocity . Thus if two objects have the same momentum, the lighter object will have a larger velocity.
Which has the greatest impulse?
Explain. Balloon B has the greatest impulse. Impulse is equal to momentum change.
What is impulse equivalent to?
The impulse experienced by the object equals the change in momentum of the object . In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
Which truck has more momentum Why?
A moving truck has more momentum than a car moving at the same speed because the truck has more mass. A fast car can have more momentum than a slow truck.
