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