Force and Motion

A push or pull on an object that can cause it to change its velocity.

The change in position of an object over time.

The amount of matter in an object, usually measured in kilograms.

Gravity pulls objects toward each other, with the strength depending on their masses.

Gravity increases as the mass of an object increases.

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

1. Static friction 2. Sliding friction 3. Rolling friction 4. Fluid friction.

The forces cancel each other out or result in a net force.

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

The tendency of an object to resist changes in its state of motion.
