What happens to acceleration when a ball bounces?
After the initial impact, the ball rapidly decelerates or rather accelerates in a negative direction. The velocity of the ball still points downward as it deforms, but acceleration on the ball is beginning to point back upward as the forces from the reaction overcome gravity.

Rather each picture should be viewed individually.
Does a bouncing ball have constant acceleration?
Acceleration on the ball is constant and always in downward direction so it would be negative. a=−g for all time.
What force causes bouncing?
Gravity pulls the ball toward the ground, slowing the ball down so that each bounce is shorter and shorter, until eventually the ball stops bouncing. The force of the ball hitting the hard ground puts an equal force back onto the ball, causing it to bounce up.
Why does a bouncy ball bounce?
When the bouncy ball is stretched, these polymer chains uncoil and straighten. When released, the chains coil back up again. This makes the material stretchy and bouncy. When your ball bounces, it is squishing when it hits the ground, then un-squishing as it bounces back up.
What happens when a ball bounces?
When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. The ball slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat.
What affects the bounce of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Which force will determine the quality of bounce *?
According to he third law of motion given by Newton that every action have a equal and opposite reaction . Hence the reaction force causes a ball to bounce.
Why do things bounce physics?
The faster an object moves, the higher its kinetic energy. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
What is the vertical acceleration of a ball when it bounces?
Vertical acceleration is change in vertical momentum … so it has to be in the opposite direction to g when the ball bounces, and all the downward momentum that it got during the quite long time in the air has to be reversed in the very short time on the ground.
What is the slope of the force vs acceleration graph?
The Force vs acceleration graph has force in the y-axis and acceleration in the x-axis, therefore: y/x is= Force/acceleration. Force/acceleration = mass. Slope of Force vs acceleration is equal to mass.
What does force/acceleration mean?
The Force vs acceleration graph has force in the y-axis and acceleration in the x-axis, therefore: y/x is= Force/acceleration. Force/acceleration = mass.
What is the unit of the force vs acceleration graph?
The units of the slope of force vs. acceleration are N/ (m/s^2). This simplifies to kg. The slope represents the mass of the pulley. Click to see full answer. Considering this, what does a force vs acceleration graph represent?
