If a body experiences a net zero unbalanced force, then what can be said about the motion of the body?

What can you say about the motion of a body if its displacement-time graph is a straight line?
An object experiences a net zero external unbalanced force. Isit possible for the object to be traveling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If no, provide a reason.
Which of the following effect cannot be produced by an unbalanced force acting on a body?$(a)$. change in speed of the body$(b)$. change in shape of the body$(c)$. change in direction of motion of the body$(d)$. change in state of rest of the body
What should be the angle between the direction of force and the direction of motion of a body so that the work done is zero?
If the body is found to be accelerated, is the force acting on it balanced or unbalanced?
What can you say about the motion of a body if its speed-time graph is a straight line parallel to the time axis?
Define the terms 1.Net force 2.Free body diagrams
Which of the two can be zero under certain conditions : average speed of a moving body or average velocity of a moving body ?
Give one example each where:(a) a force moves a stationary body.(b) a force stops a moving body.(c) a force changes the speed of a moving body.(d) a force changes the direction of a moving body. (e) a force changes the shape (and size) of a body.
Explain why, the motion of a body which is moving with constant speed in a circular path is said to be accelerated.
One-joule work is said to be done when (a) a force of 1 N displaces a body by 1 cm (b) a force of 1 N displaces a body by 1 m (c) a force of 1 dyne displaces a body by 1 m (d) a force of 1 dyne displaces a body by 1 cm
According to the third law of motion when a body exerts a force on another body then the other body also exerts force and both are equal and opposite. So when earth exerts a force on a falling apple then the force of the same magnitude should be exerted by the apple also towards earth. So why don't the earth moves towards the apple as force is equal?
What can you say about the motion of a body whose distance-time graph is a straight line parallel to the time axis ?
When we talk of a force acting on a body, it usually means:$(a)$. electrical force$(b)$. balanced force$(c)$. unbalanced force$(d)$. nuclear force
When a heavier body collides with a lighter body then which one will experience greater force?
