Amplify- Force and Motion Chapter 1

Front

What is force?

Back

A push or pull that can cause motion.

Front

What is friction?

Back

A force that acts in the opposite direction of motion, slowing objects down.

Front

What must happen for an object to stop moving?

Back

A force must act in the opposite direction of the object's motion.

Front

What is the relationship between force and motion?

Back

Force causes changes in the motion of an object.

Front

What happens when two objects collide?

Back

They exert forces on each other, which can change their motion.

Front

What is the effect of friction on different surfaces?

Back

Friction is greater on rough surfaces (like carpet) than on smooth surfaces (like a bare floor).

Front

What is the role of thrusters in motion?

Back

Thrusters can change the direction and speed of an object, such as slowing it down or pushing it in the opposite direction.

Front

What is the difference between speed and velocity?

Back

Speed is the rate of motion, while velocity includes direction.

Front

How does gravity affect motion?

Back

Gravity pulls objects toward each other, affecting their motion and speed.

Front

What is inertia?

Back

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