Physics Final Exam

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 do you calculate the mass of an object using momentum and velocity?

Back

Mass can be calculated using the formula m = p/v, where p is momentum and v is velocity.

Front

What is the standard metric unit for momentum?

Back

The standard metric unit for momentum is kg m/s.

Front

Which object has greater momentum: a 0.05 kg object rolling at 0.2 m/s or a 0.15 kg object rolling at 2 m/s?

Back

The 0.15 kg object rolling at 2 m/s has greater momentum.

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 = force × time.

Front

What is the standard metric unit for force?

Back

The standard metric unit for force is the Newton (N).

Front

How do you calculate impulse if a force of 20 N acts for 0.3 s?

Back

Impulse = 20 N × 0.3 s = 6 N*s.

Front

What is the standard metric unit for length?

Back

The standard metric unit for length is the meter (m).

Front

What is the standard metric unit for time?

Back

The standard metric unit for time is the second (s).

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.
