Forces and Motion Concepts

Front

What causes objects to move, stop moving, or change direction?

Back

Unbalanced forces.

Front

What can change an object's velocity and acceleration?

Back

Unbalanced forces.

Front

What does the velocity of an object refer to?

Back

The direction of the motion of an object and it's speed.

Front

What do objects with more mass require to accelerate?

Back

More force.

Front

How can an object's positive and negative movements be modeled?

Back

Using a motion map or time-position graph.

Front

What should be used to describe motion?

Back

An established relative frame of reference, such as a tree or a mountain.

Front

What is the net force?

Back

The amount of force causing the object to change acceleration.

Front

What happens to an object subjected to balanced forces?

Back

It does not change its motion (sum of F=0).

Front

What happens to an object subjected to unbalanced forces?

Back

It changes its motion over time (sum of F≠0).

Front

What can affect acceleration?

Back

The mass of the object and/or the force applied.
