Front

What explains why objects resist changes in their state of motion?

Back

Inertia is the property of matter that causes it to resist changes in its state of motion.

Front

What direction will an object move if a force is applied to the right?

Back

The object will move to the right.

Front

What is net force?

Back

Net force is the combined forces acting on a particular object.

Front

According to Newton, what kinds of objects are affected by gravity?

Back

All objects in the universe are affected by gravity.

Front

If an object is accelerating, what can we say about the forces acting on it?

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

Front

What is friction?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, depending on their masses and the distance between them.
