Unit 4 Vocabulary & Practice - Forces & Motion

Select all that apply to ACCELERATION.

• Change in speed, direction or both

• Acceleration is the change in velocity

• The rate of change of position (or distance traveled) with respect to time

• Increasing speed, decreasing speed, and change in direction

• A change in motion caused by an unbalanced force acting on an object

Velocity is...

• A change in motion caused by an unbalanced force acting on an object.

• The rate of change of position (or distance traveled) with respect to time

• Measurement of speed and direction of an object

• The tendency of a physical object to remain still or continue moving unless force is applied

Select the choice that does NOT apply to Speed.

• The rate of change of position (or distance traveled) with respect to time

• Measurement of speed and direction of an object

• 55 mph

• Measured in meters per second or m/s

• A scalar quantity

Which term matches the provided image?

Calculate the Net Force using the image provided.

• Net Force = 0N

• Net Force = 9N

• Net force = 5N

• Net Force = -5N

The image provided shows...

• inertia

• balanced forces

• unbalanced forces

• at rest

If two people are playing a game of tug-o-war and there is a greater force applied on the left than on the right, this is describing which of the following...

• inertia

• balanced forces

• unbalanced forces

• speed

The state of an object when it is not in mention is ___________.

• gravity

• balanced forces

• unbalanced forces

• at rest

The sum of all forces being applied on an object is called __________.

• force

• net force

• inertia

• unbalanced forces

If the forces are unbalanced and applied on the same side of the object, we would __________ the forces in order to calculate the Net Force.

• divide

• subtract

• add

• multiply
