A skateboard rolling down a hill with increasing speed

Answer 1

The example that shows an object acted on by two balanced forces is **"A car moving at a constant speed in a constant direction."** In this scenario, the forces acting on the car, such as the driving force and the friction/air resistance, are balanced, resulting in constant velocity.

Answer 2

Speed, unlike acceleration or velocity, does NOT specify _______.(1 point)

Time

Answer 3

Speed, unlike acceleration or velocity, does NOT specify **Direction**. Speed is a scalar quantity, which means it only has magnitude, whereas both acceleration and velocity are vector quantities that include both magnitude and direction.
