What happens to the motion of an object when the forces acting on it are balanced?

• The object speeds up.

• The object slows down.

• The object changes direction.

• The object remains moving at the same speed or stays still.

Using Newton's Second Law, if the mass of an object is increased while the force applied remains the same, what will happen to the acceleration?

• It will increase.

• It will decrease.

• It will stay the same.

• It will become zero.

If you push a toy car gently and then push it with more force, what difference will you notice in the car's motion?

• The car moves slower when pushed harder.

• The car moves faster when pushed harder.

• The car's motion does not change.

• The car moves in the opposite direction.

Explain why astronauts appear weightless in space despite gravity acting everywhere in the universe.

• There is no gravity in space.

• Astronauts are too far from Earth to be affected by gravity.

• Astronauts are in free fall around the Earth, creating the sensation of weightlessness.

• The spacesuit cancels out the effects of gravity.

Design an experiment to test how surface texture affects the amount of friction between two surfaces.

• Measure how long a block slides on different surfaces.

• Drop various objects and see which hits the ground first.

• Push a block with varying forces and measure the distance it travels.

• Shine a light on surfaces to see the reflection.
