Final Review

Front

What is the acceleration of an object in free fall?

Back

The acceleration of an object in free fall is constant and is approximately 9.81 m/s², regardless of its mass.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What is static friction?

Back

Static friction is the force that prevents two surfaces in contact from sliding past each other.

Front

What is gravity?

Back

Gravity is the attractive force between two objects that depends on their masses and the distance between them.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, and it is a vector quantity.

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object and does not change with location.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.

Front

What is centripetal acceleration?

Back

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

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.
