Force - JSS1 Basic science Past Questions and Answers - page 2
What is an example of a contact force?
An example of a contact force is the force exerted when you push a door to open it.
Can you give an example of a non-contact force?
An example of a non-contact force is the gravitational force exerted by the Earth on an object, even when they are not in physical contact.
How does frictional force affect the motion of objects?
Frictional force opposes the motion of objects sliding against each other, causing them to slow down or come to a stop.
What determines the strength of the gravitational force between two objects?
The strength of the gravitational force between two objects depends on their masses and the distance between them. The greater the masses and the shorter the distance between the objects, the stronger the gravitational force.
What role does tension force play in everyday life?
Tension force is often observed in everyday scenarios such as when a person pulls on a rope to lift an object or when a string holds up a hanging decoration.
How do magnets interact with each other?
Magnets can either attract or repel each other depending on the orientation of their poles. Like poles repel each other, while opposite poles attract. This interaction is due to the magnetic force between the magnets.
