Quick Answer: Can A Tiny Bullet Have More Momentum Than A Huge Truck?

Does direction matter for momentum?

Momentum is not only dependent on the mass and speed of the target.

In a given direction, velocity is distance, so an object’s momentum therefore depends on the direction of motion.

This means that an object’s velocity will shift whether the object accelerates or slows down..

Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

Why do skaters pull their arms in to move faster?

The principle of the conservation of angular momentum holds that an object’s angular momentum will stay the same unless acted upon by an outside force. This explains why a figure skater spins faster when she tucks her arms in close to her body.

How much momentum does it take to stop a running back?

Under those circumstances the defender would have three times the momentum of the relatively stationary running back and hit him with roughly two thirds of a ton of force. Defenders running full speed, however, face a risk: the ball carrier could sidestep an overly aggressive player.

What happens when you double the mass?

If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

Can momentum be lost?

Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. If there are only two objects involved in the collision, then the momentum lost by one object equals the momentum gained by the other object.

Can a lighter object have more momentum than a heavier one how?

Question: Can A Lighter Object Have More Momentum Than A Heavier One? … No, Because Momentum Is Independent Of The Mass Of The Object.

What has more momentum a car or a truck?

The truck has more momentum than the car. By momentum, we mean inertia in motion. Momentum is the mass of an object multiplied by its velocity. A moving truck has more momentum than a car moving at the same speed because the truck has more mass.

Is angular momentum always conserved?

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.

What kind of quantity is momentum?

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

What is the force required to stop a moving object?

Explanation: an external force is required to stop a moving object because the external force creates a sort of friction or a blockage for the moving object helping it to stop.

What happens when two objects with the same momentum collide?

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.

How can a tennis ball and a bowling ball have the same momentum?

The force of gravity pull the balls down and changes its momentum. … So, the tennis ball will change velocity more, but it has less mass, so it can have the same momentum change as the bowling ball, which will not affect velocity much but has a bigger mass.

What causes and is equal to a change in momentum?

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. … The collision would change the halfback’s speed and thus his momentum.

Which ball has a greater mass pingpong ball or tennis ball?

For the first scenario, a tennis ball has a greater mass than a ping-pong ball since it is heavier where its mass ranges from 54 – 56 grams while the ping-pong ball is only 2.7 grams. For the second scenario, the tennis, and ping-pong ball was hit with the same amount of force.

Why does it take a large truck longer to stop?

Terms in this set (10) The truck has more mass thus, more momentum. So the truck needs a larger force to stop it. … a fast moving car has a greater velocity and more momentum than a slow moving car of the same mass.

Is angular momentum conserved?

The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.

Can a bullet have the same momentum as a truck?

Yes. Momentum is just the mass of the object times the velocity. P=MV where the P is momentum, M is mass and V = is velocity. An object that is small in mass, like a bullet, can have the same momentum as a truck as long as it going much faster than the truck.

Can objects with different masses have the same momentum?

When comparing the kinetic energy of two objects, the velocity of an object is of double importance. So if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity.

Do all moving objects have momentum?

If an object is in motion (on the move) then it has momentum. Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion. … Momentum depends upon the variables mass and velocity.

How can the skaters angular momentum be changed?

According to the law of the conservation of angular momentum, the angular momentum of an object will not change unless external torque is applied to the object. When spinning, a figure skater will bring his or her arms closer to his or her body in order to increase their angular velocity and rotate faster.
