### Force

In Science, force, usually means either a push or pull.

Think of a game of ten Pin bowling

The moving object- the ball exerts a pushing force against anything it hits-the ten pins!

What is force?
Where are the forces?
• Can you see forces?
• Can you see objects affected by forces?
• Forces can make things go faster or slower.
How do we measure force?
• We measure force in newtons
• We use an instrument called a spring balance known as force meter or newton meter.
Gravitational force
• What happens when a ball is thrown upwards?
• What happens when you jump up?
• What happens to ripe fruits that grow on trees?
Air resistance
• Air resistance pushes against a moving car and slows it down.
• With a parachute, it is an advantage.
Balanced forces
• Table is pushed upwards by the floor while table is pushed down by gravity.
So now you know what force is
• Can you name the forces acting in the pictures below?
