Physics HS Quiz 2

What is displacement?

• Total distance traveled

• Shortest path from start to finish

• Speed multiplied by time

• A measure of acceleration

An object is thrown upward. At the peak of its motion, its velocity is:

• Positive

• Zero

• Negative

• Equal to its acceleration

What does the area under a velocity-time graph represent?

• Speed

• Displacement

• Force

• Acceleration

A car accelerates from 0 to 20 m/s in 5 seconds. What is its acceleration?

• 2 m/s²

• 4 m/s²

• 5 m/s²

• 10 m/s²

Which of the following is an example of uniformly accelerated motion?

• A car cruising at constant speed

• A ball rolling down a hill with constant acceleration

• A pendulum swinging back and forth

• A person walking at a steady pace

If an object is in equilibrium, the net force acting on it is:

• Equal to its weight

• Zero

• Constant

• Equal to its mass

The force that resists motion between two surfaces is called:

• Tension

• Friction

• Normal force

• Centripetal force

Which of the following affects the force of friction?

• Surface area of contact

• Type of surfaces in contact

• Speed of the object

• Shape of the object

• Frictional force

• Normal force

• Centripetal force

• Gravitational force
