The acceleration due to gravity on earth is 10 ms⁻² while on the moon it is 1.6 ms⁻².
If a person whose weight on earth is 500 N goes to the moon.
His weight on the moon will be:
51.6 N.
31.25 N.
500 N.
80.0 N.
Which of the following is correct?
It is NOT possible for a body to be at rest and yet have an acceleration.
A body can be accelerating in a direction opposite to that of its velocity.
It is possible for the speed of a body to change without the body accelerating.
A change in the velocity of an object implies a change in its speed.
The air resistance experienced by a moving car can be reduced by:
Reducing the speed.
Driving on a tarred road.
Increasing the speed.
Driving at steady speed.
A body falling in air experiences terminal velocity when its:
Weight is negligible.
Acceleration is zero.
Velocity decreases at a constant rate.
Velocity is zero.
A hollow plastic ball and a solid metal ball all of the same external radius are both released from rest in a vacuum chamber.
After falling for one minute, they will have the same:
Kinetic energy.
Speed.
Change in momentum.
Inertia.
