What is a “force” in physics?
A push or a pull
Only something heavy
Only gravity
Only magnetism
Which one is an example of motion?
Tree standing still
A car moving down a street
Book closed on shelf
Rock lying on ground
What happens when unbalanced forces act on an object?
It stays the same
It splits in two
It disappears
It changes its motion
Which law says “an object at rest stays at rest and an object in motion stays in motion”?
Law of Conservation of Energy
Newton’s First Law
Newton’s Second Law
Newton’s Third Law
What does friction do?
It makes motion invisible
It stops gravity
It resists motion
It speeds up motion
Which force pulls objects toward the Earth?
Magnetism
Electricity
Gravity
Friction
What happens if you push an object harder?
It stays the same
It floats up
Its motion can change more
It becomes invisible
Why is it harder to push a heavy object than a light one?
Because it has more mass
Because it’s moving
Because it’s bigger
Because it’s colourful
Which law states that Force = Mass × Acceleration?
Newton’s Second Law
Law of Momentum
Newton’s First Law
Newton’s Third Law
What is acceleration?
Distance only
Time only
The change in speed or direction
Speed only
True or False: If forces on an object are balanced
the object will continue moving at constant velocity.
False
True
True or False: Friction can slow down or stop motion.
True
False
True or False: Gravity only affects things that are moving.
True
False
True or False: Increasing the net force on an object increases its acceleration.
False
True
True or False: A heavier object always accelerates slower than a lighter one under the same force.
False
True
True or False: Magnetism and gravity are both forces.
True
False
