Topic 3 Lesson 1 Review

Front

What is a reference point?

Back

A place or object used for comparison to determine if another object is in motion.

Front

What is the net force if an object has a force of 1.3 N to the right?

Back

1.3 N right

Front

Why is all motion described as relative?

Back

Because everything in the universe is constantly in motion, so it depends on your frame of reference.

Front

What type of force is kinetic friction?

Back

Contact Force

Front

During which segments of a speed-time graph are the forces acting on the object balanced?

Back

Q and S

Front

What is motion?

Back

The change in position of an object over time.

Front

What is a contact force?

Back

A force that requires physical contact between two objects.

Front

What is an example of a non-contact force?

Back

Gravity.

Front

What does it mean for forces to be balanced?

Back

The net force acting on an object is zero, resulting in no change in motion.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction.
