What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

Give an example of a balanced force.

Back

A train moving at a constant speed in the same direction.

Front

What does a graph showing constant speed look like?

Back

A straight line that slopes upwards at a consistent angle.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, meaning it is speeding up.

Front

What is deceleration?

Back

Deceleration is the rate of decrease in velocity, meaning it is slowing down.

Front

What is net force?

Back

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

Front

How do you calculate net force?

Back

Add up all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What does it mean if the net force is 0?

Back

It means that the forces acting on an object are balanced, resulting in no change in motion.

Front

Why is the net force 0 when two elephants pull with the same force in opposite directions?

Back

Because they are both pulling the same amount of force in opposite directions.

Front

What is an example of unbalanced forces?

Back

A basketball being passed to a teammate.
