Forces, Net Force & Diagrams Practice

Front

What is a force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

How do you determine if forces are balanced or unbalanced?

Back

If the net force is zero, the forces are balanced. If the net force is greater than zero, the forces are unbalanced.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it.

Front

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

Back

An object in motion will continue to move at a constant speed in a straight line when balanced forces act on it.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

What is inertia?

Back

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