AP Physics 1 Unit 2 Review

Front

What is the formula for calculating average force?

Back

Average Force = Change in Momentum / Time = (m * Δv) / Δt

Front

What is the definition of unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate, resulting in a change in motion.

Front

What is normal force?

Back

Normal force is the force exerted by a surface that supports the weight of an object resting on it, always acting perpendicular to the surface.

Front

What is the relationship between mass, acceleration, and force according to Newton's second law?

Back

F = m * a, where F is force, m is mass, and a is acceleration.

Front

What happens to an object in motion when balanced forces act on it?

Back

An object in motion will remain in motion at a constant velocity when balanced forces act on it.

Front

How do you calculate acceleration?

Back

Acceleration = Change in Velocity / Time = (v_f - v_i) / t.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, reducing its speed or preventing it from moving.

Front

What is the significance of the gravitational force on an object?

Back

Gravitational force is the force that attracts two bodies towards each other, affecting the weight of the object.

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
