Force and Motion Review

Front

What is force?

Back

A force is a push or pull that can cause an object to move, change direction, or stop.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass, causing objects to fall towards the Earth.

Front

What is frictional force?

Back

Frictional force is the resistance that one surface or object encounters when moving over another.

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object.

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 formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
