MOTION

A toy car moves in a straight line. A graph of the car’s distance from the

starting point over 18 seconds is shown below.

• A

• B

• C

• D

The graph shows the progress made by a beetle moving along a straight line. If the beetle keeps moving at the same speed how long will it take to travel 10cm.

• 4 second

• 6 seconds

• 20 seconds

• 25 seconds

What is the total distance traveled by the car?

Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

Speed of an object is equal to the magnitude of velocity if-

• the object is travelling in uniform circular motion

• the object is travelling along a straight path

• the initial and final positions are same

• none of these

Which term means speed with a direction?

• Speeding
• Acceleration
• Velocity
• Gravity

The force that opposes the motion of two surfaces that are in contact and are sliding over each other.

• Static Friction
• Kinetic Friction

Calculate the acceleration for segment A.

• 2 m/s²
• 20 m/s²
• -2 m/s²
• 0 m/s²

The sum of all movements from start to the end of motion is best described as____.

• distance

• displacement

• motion

• donkey

Which runner stopped for a rest?

• Albert
• Bob
