Which could be an example of an unbalanced force?

• Earth orbiting the Sun

• A ball at the top of a hill that is not moving

• A Skydiver falling off a helicopter

• A plate sitting on a dining table

Force = Mass x _________

• Velocity

• Weight

• Acceleration

• Temperature

force is calculated as;

• Force = Mass x Gravitational field strength

• Force = Gravitational field strength ÷ Mass

• Force = Mass ÷ gravitational field strength

• Force = Mass x Upthrust

Ragnar floats on the water even though gravity is pulling him down? Why is this possible?

• He is very light in weight so he cannot sink.

• He is using backstroke style so, he is able to float.

• There is a balance in the buoyancy and gravity as he swims.

• Upthrust is greater than the force of gravity as he swims.

• 36N

• 160N

• 360N
