Practice for Physics Final 2024

Front

What type of force(s) will cause a change in an object's motion (an acceleration)?

Back

Unbalanced forces cause a change in an object's motion.

Front

What is the difference between speed and velocity?

Back

Velocity has direction, while speed does not.

Front

What does positive acceleration indicate in a motion diagram?

Back

Positive acceleration indicates an increase in velocity over time.

Front

Which segment of a velocity-time graph shows constant velocity?

Back

The segment labeled BC shows constant velocity.

Front

What is the rate at which velocity changes called?

Back

Acceleration is the rate at which velocity changes.

Front

Define speed in the context of physics.

Back

Speed is the distance traveled per unit of time, without regard to direction.

Front

Define velocity in the context of physics.

Back

Velocity is the speed of an object in a specific direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the significance of a zero net force acting on an object?

Back

A zero net force means the object will maintain its current state of motion (either at rest or moving at constant velocity).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates a decrease in velocity over time.
