Topic 3 Lesson 1 Review

Front

What is Tension?

Back

Tension is a contact force that is transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object.

Front

How do you determine the direction of net force?

Back

The direction of the net force is determined by the direction of the greater force acting on the object.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are in physical contact with each other.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without physical contact, such as gravitational force.

Front

What is the significance of a frame of reference?

Back

A frame of reference is a system for specifying the precise location of objects in space and time, which is essential for describing motion.

Front

What does a speed graph represent?

Back

A speed graph shows how the speed of an object changes over time, indicating periods of acceleration, deceleration, and constant speed.

Front

What does it mean to open a parachute?

Back

Opening a parachute increases air resistance, slowing down the descent of the parachutist.
