A measure of the amount of distance an object moves in a given amount of time.                Average Speed = Distance / Time

The rate at which velocity Changes

Speed of an object in a particular direction.

The tendency of an object to resist any change in motion.

Ex. A seat belt is used to stop your inertia. If you are moving forward and the car stops, you will continue to go forward until the seat belt stops you.

A measure of the pull of gravity on a specific mass.

A contact force that resists motion between two objects

The unit scientists measure force in

A force of attraction between objects due to their masses

Friction between a moving object and the air around the objec

If a ping pong ball and a basketball were both dropped at the same time from the roof of our school, which would hit the ground with a greater force?

Removing air to create a vacuum, like in space, increases / decreases the amount of air resistance acting on a moving object. (Circle one)

Danaya is moving heavy furniture by sliding it across the floor. She puts a blanket underneath the furniture. Why did this help her? (MS-PS2-2)

Which pair of objects has the largest gravitational force?

Place a ball in a box and slowly push the box. Abruptly stop the box. The ball will keep moving.

This is an example of

When you push on the pedals, your bicycle accelerates. You are increasing the speed of the bicycle by applying force to the pedals.

This is an example of

when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

This is an example of

A change in an object’s position over time.
