Understanding Motion Graphs and Net Force

What is the initial velocity of the car in the scenario described?

• 25 m/s

• 20 m/s

• 10 m/s

• 15 m/s

What is the net force on the car when it is moving at a constant velocity?

• Variable

• Negative

• Positive

• Zero

What does a zero slope on a velocity-time graph indicate about acceleration?

• Negative acceleration

• Zero acceleration

• Variable acceleration

• Positive acceleration

What is the acceleration of the car when it is slowing down?

• 3 m/s²

• 5 m/s²

• 0 m/s²

• -5 m/s²

How is the net force calculated when the car is decelerating?

• Mass times acceleration

• Mass times velocity

• Velocity divided by time

• Force divided by mass

What is the net force on the car when it is decelerating?

• 5500 N

• 3300 N

• -3300 N

• -5500 N

What is the acceleration of the car when it speeds up again?

• -5 m/s²

• 5 m/s²

• -3 m/s²

• 3 m/s²

What is the net force on the car when it is accelerating?

• -5500 N

• 5500 N

• -3300 N

• 3300 N

What role does the road force play when the car is accelerating?

• It has no effect

• It propels the car forward

• It slows the car down

• It opposes the motion

What is the relationship between motion graphs and Newton's second law?

• Motion graphs illustrate acceleration

• Motion graphs show velocity only

• Motion graphs determine mass

• They are unrelated
