The displacement, time, and direction
Explanation:
The gravitational potential energy is given by :
P = mgh
The kinetic energy of an object is given by :
As the ball reaches the bottom of the ramp, its potential energy decreases and kinetic energy increases.
It imply that, when the ball at the top most height, its gravitational potential energy is maximum and zero kinetic energy and when ball reaches the bottom of the ramp, it will have maximum kinetic energy and zero potential energy.
Answer:
D.They are equal in magnitude and opposite in direction
Explanation:
- Newton's third law states that the action force is always associated with a reaction force.
- When a body 'A' exerts a force on body 'B', it is called the force of action.
- When the body 'B' in turn resist the force of 'A' is called the reaction force. It is the reactive force acted upon by the body 'B' on 'A'.
- This reaction force is equal in magnitude of the action force.
- If the two bodies remain in the same horizontal line, the 'A' exerts a force in the direction towards 'B' and the body 'B' exerts a reaction force in the direction towards 'A'.
- Hence, the two forces that are exerted by the bodies are equal in magnitude and opposite in direction.
Answer:
false
Explanation:
every object will always have the force of gravity acting upon it.
