• The force needed increases

• The force needed becomes zero

Why does a sprinter need to apply a larger force at the start of a race?

• To maintain constant speed

• To decelerate quickly

• To build up speed

• To stop immediately

Which of the following is NOT a type of force mentioned in the text?

What effect does the force of a racquet swing have on a tennis ball?

• It causes the ball to decelerate.

• It causes the ball to change color.

• It causes the ball to accelerate in the direction of the swing force.

• It causes the ball to stop moving.

In the example of a swimmer, what is the relationship between the force exerted by the swimmer and the wall?

• The swimmer's force is greater.

• The wall's force is greater.

• They are equal in size and opposite in direction.

• They cancel each other out.

What is angular motion?

• Motion in a straight line

• Motion around an axis

• Combination of linear and angular motion

• Motion in a zigzag path

What is general motion?

• Motion in a straight line

• Motion around an axis

• Combination of linear and angular motion

• Motion in a spiral path

What is the equation for momentum?

• Momentum = Mass + Velocity

• Momentum = Mass × Velocity

• Momentum = Mass / Velocity

• Momentum = Velocity - Mass

What happens to an object's momentum when a larger force is applied for a longer time?

• The momentum decreases

• The momentum remains the same

• The momentum increases

• The momentum becomes zero
