1 answer:
Answer:
Acceleration
Explanation:
The choice from the given option which is not a force is acceleration.
Acceleration is defined as the rate of change of velocity of a body with time;
Acceleration =
Force is a pull or push on a body. The product of mass and acceleration is force.
- Thrust is a form of force
- Gravity is a force acting on bodies with masses.
- Friction is a force that opposes motion,

Answer:
when the ball is at rest in his coach's hands.
Explanation:
The forces on the basketball are balanced when the basketball is not experiencing any acceleration. This happens when the ball is in his coach's hand: in fact, at that moment the ball is at rest, so it means that its acceleration is zero. According to Newton's second law, this also mean that the net force on the basketball is zero, so the forces on the ball are balanced:
where F is the net force, m is the mass of the ball and a is the acceleration.
