Forces Review

Front

What is friction?

Back

Friction is a force between an object and the surface it is moving over.

Front

What does it mean to infer?

Back

To infer means to reach a conclusion using evidence and reasoning.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every force acting on an object, that object exerts an equal force in the opposite direction on the first object.

Front

What is velocity?

Back

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

Front

What are balanced forces?

Back

Balanced forces occur when all forces acting on an object are equal, resulting in no 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 an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, which can slow it down or prevent it from moving.

Front

What is the formula for calculating force?

Back

The formula for calculating force is 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.
