Forces

Front

What happens to an object when unbalanced forces are applied?

Back

The object will move in the direction of the larger force.

Front

Define net force.

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is friction force?

Back

Friction force is the force that opposes the motion of an object when it is in contact with another surface.

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is the effect of balanced forces on a moving car?

Back

A car moving with constant motion (in a straight line at the same speed) experiences balanced forces.

Front

What role does friction play when going downhill?

Back

Friction makes it harder for an object, like a boy on a hill, to move downwards.

Front

What is the relationship between mass and force in Newton's second law?

Back

According to Newton's second law, force equals mass times acceleration (F=ma).
