Forces and Motion Flashcard Review

Front

What is a force?

Back

A force is an action exerted on a body to change its state of motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often caused by the contact between surfaces.

Front

What does it mean for a force to be unbalanced?

Back

An unbalanced force occurs when one force acting on an object is greater than the other forces, causing the object to move in the direction of the greater force.

Front

What happens to an object at rest when a small force is applied?

Back

If the force is too small to overcome friction, the object will remain at rest.

Front

What is motion?

Back

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

Front

What is the relationship between force and motion?

Back

A force can cause an object to start moving, stop moving, or change direction.

Front

What is an example of a balanced force?

Back

When two people push on opposite sides of a box with equal force, the box does not move.

Front

What is inertia?

Back

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

Front

How does mass affect motion?

Back

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

Front

What is the effect of applying a greater force to an object?

Back

Applying a greater force to an object will cause it to accelerate and move faster.
