What is Net Force?

Back

Net Force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of movement.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion. It slows down moving objects and can prevent them from starting to move.

Front

What determines the strength of gravitational pull between two objects?

Back

The strength of gravitational pull is determined by the masses of the objects and the distance between them. Greater mass and closer distance result in a stronger gravitational pull.

Front

How does mass affect weight on different planets?

Back

Weight is the force of gravity acting on an object's mass. An object's weight varies on different planets due to differences in gravitational pull.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is the direction of net force if an object is moving left with a net force of 4N?

Back

The direction of the net force is to the left, as it is the direction of the object's movement.

Front

What happens to an object's motion when friction is present?

Back

Friction acts to slow down the motion of an object, making it harder for the object to move.

Front

Which object experiences the weakest gravitational pull towards another object?

Back

The object with the least mass will experience the weakest gravitational pull towards a larger mass.

Front

How does the mass of a planet affect an object's weight on it?

Back

An object will weigh less on a planet with lower mass compared to a planet with higher mass due to weaker gravitational pull.

Front

Give an example of Newton's Third Law of Motion.

Back

A rocket launches upward as the gases it expels push downward with equal force.
