Amplify- Force and Motion Chapter 1

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the object's movement.

Front

What happens to an object when friction acts on it?

Back

Friction slows down the object, reducing its speed.

Front

Is there friction on Earth?

Back

Yes, there is friction on Earth; it is a common force that affects the motion of objects.

Front

How does the surface affect friction?

Back

Different surfaces have different levels of friction; for example, friction on carpet is generally greater than on a bare floor.

Front

What is the relationship between force and motion?

Back

A force must be applied to an object to change its state of motion, whether to start moving, stop, or change direction.

Front

What direction must a force come from to start moving an object?

Back

A force can come from any direction to start moving an object.

Front

What are the five ways an object's motion can change?

Back

1. Speed Up 2. Slow Down 3. Change Direction 4. Start Moving 5. Stop Moving.

Front

What is the effect of a stronger force on an object's motion?

Back

A stronger force will cause the object to accelerate faster and reach its destination sooner than a weaker force.

Front

What is an example of an object speeding up?

Back

A car accelerating from a stoplight is an example of an object speeding up.

Front

What is the role of thrusters in motion?

Back

Thrusters apply force to an object, causing it to move in the opposite direction of the force applied.
