Worksheet time: 5mins
What is a force?
A force is a type of energy.
A force is a fixed quantity that cannot change.
A force is an interaction that causes a change in motion.
A force is a measurement of speed.
Name two types of forces.
Electric force
Nuclear force
Gravitational force, Frictional force
Magnetic force
What is the force that pulls objects towards the Earth?
Gravity
Electromagnetism
Friction
Magnetism
What do we call the force that opposes motion?
Friction
Gravity
Inertia
Momentum
What is friction?
Friction is the temperature increase caused by two surfaces rubbing together.
Friction is the force that opposes the relative motion of two surfaces in contact.
Friction is the force that enhances the motion of two surfaces in contact.
Friction is the energy lost when two surfaces slide over each other.
Can you give an example of a contact force?
Gravity
Friction
Magnetism
Tension
What is a non-contact force?
A non-contact force is only applicable in space.
A non-contact force is a force that acts on an object without physical contact.
A non-contact force can only be observed in liquids.
A non-contact force requires physical touch to act.
What happens to an object when a force is applied?
The object will always remain stationary.
The object will spontaneously combust.
The object will float in the air without support.
The object may accelerate, change direction, or deform.
How does gravity affect objects on Earth?
Gravity has no effect on the motion of objects.
Gravity only affects large objects like planets.
Gravity pushes objects away from the Earth.
Gravity causes objects to be pulled towards the Earth, giving them weight and influencing their motion.
What is the difference between push and pull forces?
Pull forces can only be applied vertically.
Push forces are always stronger than pull forces.
Push forces move objects away; pull forces draw objects closer.
Push and pull forces are the same in all situations.
