What can make an object start moving or change its motion?

• The temperature of the object increasing.
• A force applied to the object.
• Gravity pulling the object down.
• The object's color changing.

Which force is responsible for attracting iron to a magnet?

• Electrostatic force
• Friction
• Gravity
• Magnetism

What effect does a balanced force have on an object?

• A balanced force does not change the motion of an object.
• A balanced force makes an object spin faster.
• A balanced force changes the direction of an object.
• A balanced force causes an object to accelerate.

What is likely to happen when a stationary object experiences an unbalanced force?

• The object will rotate in place without moving.
• The object will explode due to the force.
• The object will remain stationary indefinitely.
• The object will start to move in the direction of the unbalanced force.

How does gravity act on objects?

• Gravity has no effect on objects on earth.

• Gravity pulls objects towards itself.

• Gravity pushes objects away from each other.

What is the main role of a pulley?

• The main role of a pulley is to change the direction of force to lift heavy objects more easily.
• To reduce the friction in moving parts of machinery.
• To create a permanent support structure for heavy items.
• To increase the weight of objects being lifted.
