Physics Final Exam Review

Front

What causes acceleration?

Back

Acceleration is caused by a net force acting on an object.

Front

What is an action-reaction pair according to Newton's Third Law?

Back

An action-reaction pair is when one object exerts a force on a second object, and the second object exerts an equal and opposite force on the first.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

How do you calculate momentum?

Back

Momentum is calculated by multiplying an object's mass by its velocity (p = mv).

Front

What does the law of conservation of momentum state?

Back

The law of conservation of momentum states that the total momentum of a closed system before a collision is equal to the total momentum after the collision.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) is calculated using the formula a_c = v^2 / r, where v is the velocity and r is the radius of the circular path.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the relationship is given by F = ma, where F is force, m is mass, and a is acceleration.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
