What is the difference between distance and displacement?

• Distance includes direction, while displacement does not.

• Distance is the length of the path traveled, while displacement is the straight line distance from start to end.

• Distance is a vector quantity, while displacement is a scalar quantity.

• Distance is measured in meters per second, while displacement is measured in meters.

Which of the following is an example of a scalar quantity?

• Velocity

• Displacement

• Speed

• Force

What does the slope of a distance vs. time graph represent?

• Acceleration

• Velocity

• Displacement

• Force

How is acceleration calculated?

• Change in speed divided by time

• Change in distance divided by time

• Initial velocity minus final velocity divided by time

• Final velocity minus initial velocity divided by time

What is the unit of acceleration?

• Kilometers per hour

• Newtons

• Meters per second squared

• Meters per second

According to Newton's first law, what will happen to an object at rest if no net force acts on it?

• It will start moving.

• It will change direction.

• It will remain at rest.

• It will accelerate.

What is the formula for Newton's second law of motion?

• F = mv

• F = ma

• F = m/v

• F = mg

According to Newton's third law, what happens when an object exerts a force on another object?

• The second object exerts a smaller force on the first object.

• The second object exerts a larger force on the first object.

• The second object exerts an equal and opposite force on the first object.

• The second object does not exert any force on the first object.
