Momentum 5.1 Practice (PPC)

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How does mass affect momentum?

Back

Momentum is directly proportional to mass. If the mass of an object increases while its velocity remains constant, its momentum will also increase.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is the formula for calculating change in momentum?

Back

The change in momentum (Δp) can be calculated using the formula Δp = FΔt, where F is the net force applied and Δt is the time duration of the force.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = FΔt.

Front

How does acceleration relate to momentum?

Back

Acceleration is the rate of change of velocity. Since momentum is dependent on velocity, a change in acceleration will result in a change in momentum.

Front

What happens to momentum during a collision?

Back

During a collision, momentum is transferred between objects. The total momentum of the system remains constant if no external forces act on it.

Front

What is the relationship between force and momentum?

Back

Force is the rate of change of momentum. According to Newton's second law, F = Δp/Δt, where F is force, Δp is change in momentum, and Δt is the time interval.

Front

What is the effect of a net force on an object's momentum?

Back

A net force acting on an object will change its momentum. The greater the force and the longer it acts, the greater the change in momentum.

Front

How can you determine the direction of momentum change?

Back

The direction of momentum change can be determined by the direction of the net force acting on the object.
