The neutron, N What can we say about the forces on an object that is not moving? There must only be one force acting on it The forces must be balanced It must be very heavy The arrows in this diagram represent the sizes of forces acting on a stationary tennis ball. What will happen to the tennis ball? It will stay still It will start to move upwards It will to move downwards What happens to the air resistance on a car as the car goes faster? It decreases It stays the same It increases Gravity is an example of what? A contact force An un-contact A non-contact force What store of energy does friction always produce? Heat Light Gravitational potential Why does an astronaut weigh less on the Moon than on the Earth? The Moon has no atmosphere The Moon has no gravity The force of gravity is weaker on the surface of the Moon than on the surface of the Earth What is the weight of a 20kg box on the 2 N 20 N 200 N Quiz Score: /10 Physics Space Key Points – – You can see satellites, the International Station, the Moon, comets, meteors, planets, stars and galaxies in the night sky.
