The diagram shows 2 boxes with forces being applied to them. In the diagram, force (F) is shown in newtons (N), acceleration (a) is shown in meters/second2 (m/s2), and the mass is shown in grams (g).
Which statement is supported by the diagram?
As the mass of an object increases, the force required for it accelerate decreases.
As the mass of an object decreases, the force required for to accelerate increases.
Heavier objects require more force than lighter objects to accelerate at the same rate.
Heavier objects require less force than lighter objects to accelerate at the same rate.
A ___________ is a push or a pull that causes an object to move.
force
speed
energy
direction
___________ is an opposing force that makes objects in motion slow down.
force
speed
friction
mass

How much force should be added to this object to bring it to equilibrium?
15N to the right
5N to the left
5N to the right

What is 'inertia of direction?'
Which has more inertia, a cricket ball or a rubber ball of the same size ? Give reason for your answer.
Why is it difficult for a fireman to hold a hose, which ejects large amount of water at a high velocity.
A man pushes a box of mass 50 kg with a force of
80 N. What will be the acceleration of the box due
to this force ? What would be the acceleration if
the mass were doubled ?
A motorcar of mass 1200 kg is moving along a straight line with a uniform velocity of 90 km/h. Its velocity is slowed down to 18 km/h in 4 s by an unbalanced external force. Calculate the acceleration and change in momentum. Also calculate the magnitude of the force required.
A body of mass 1 kg is kept at rest. A constant force of 6 N starts acting on it. Find the time taken by the body to move through a distance of 12 m.
A truck starts from rest and rolls down a hill with a constant acceleration. It travels a distance of 400 m in 20 s. Find its acceleration. Find the force acting on it if its mass is 7 tonnes.
