CIA #3 Review

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What happens when an object pushes against another object?

Back

When an object pushes against another object, it exerts a force on it, and according to Newton's third law, the second object exerts an equal and opposite force back on the first object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is Newton's third law of motion?

Back

Newton's third law states that for every action, there is an equal and opposite reaction.

Front

What is the direction of force?

Back

The direction of force is the way in which the force is applied, which can cause an object to move or change its motion.

Front

What is an example of a balanced force in everyday life?

Back

An example of a balanced force is a book resting on a table; the force of gravity pulling the book down is balanced by the normal force of the table pushing up.

Front

What is an example of friction in action?

Back

An example of friction is when you slide a book across a table; the roughness of the table surface slows the book down.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the center of the Earth, giving them weight and causing them to fall when dropped.

Front

What is the role of a trampoline when a person jumps on it?

Back

The trampoline pushes back against the person after they push down on it, allowing them to bounce back up.
