Question

is a change in position over time.
there are 3 ways to measure motion: speed, velocity, and acceleration.
speed is how fast an object is moving. we calculate speed using the formula: speed = distance/time.
velocity is speed in a given direction.
acceleration can occur when an object speeds up, slows down or a has a change in direction.
which is an example of acceleration?
riding a bike at a constant speed on a straight road
making a sharp turn while driving a car
sitting in a parked car

Explanation:

Acceleration occurs when there is a change in velocity. Velocity is speed in a given direction. Riding a bike at a constant speed on a straight road has no change in speed or direction (constant velocity), so no acceleration. Sitting in a parked car has zero velocity (no motion), so no acceleration. Making a sharp turn while driving a car involves a change in direction. Since velocity (which includes direction) changes, there is acceleration.

Answer:

Making a sharp turn while driving a car
