Question

which of the following are ways to accelerate? (check all that apply) slow down speed up turn remain at a constant speed in a straight line remain at a constant speed in a circular path remain at a constant velocity

Explanation:

To determine ways to accelerate, we use the definition of acceleration: a change in velocity (speed or direction, or both).

• Slow down: Changes speed (deceleration is a type of acceleration).
• Speed up: Changes speed (increases speed, a type of acceleration).
• Turn: Changes direction (so velocity changes, hence acceleration).
• Remain at a constant speed in a straight line: Velocity (speed and direction) is constant, so no acceleration.
• Remain at a constant speed in a circular path: Direction changes (velocity is a vector), so velocity changes, hence acceleration.
• Remain at a constant velocity: Velocity is constant (speed and direction), so no acceleration.

Answer:

• Slow down
• Speed up
• Turn
• Remain at a constant speed in a circular path
