Motion & Force

Front

What causes an object to move?

Back

Unbalanced forces

Front

What is the net force when two forces of 10 N and 15 N act in opposite directions?

Back

5 N

Front

What is friction?

Back

Friction is a force that occurs when surfaces touch each other.

Front

Who developed the Laws of Motion?

Back

Sir Isaac Newton

Front

What does Newton's 3rd Law state?

Back

For every action, there is an equal and opposite reaction.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no movement.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to move.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a)

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
