Although gravity has no effect, there is still an outward force. 

The effect of gravity is negligible, the satellite is kept in orbit by its momentum and the net force on it is zero.

The satellite is kept up by an outward force that balances the force due to gravity.

Gravity is the only force acting on the satellite and this results in an inward acceleration. 

The velocity varies with the inverse of the distance to the star 

The force varies with the inverse of the gravitational field strength 

The force varies with the inverse of the mass of the star 

The acceleration varies with the inverse of the distance to the star 

A cyclist pedals harder on their bicycle, so they accelerate up the hill. 

A cyclist pedals on their bicycle, so they go up the hill at constant speed. 

A cyclist initially pedals harder to accelerate up the hill until they get halfway and then pedals so they go up the hill at a constant speed. 

A cyclist stops peddling as they reach the bottom of a hill and their bicycle coasts up the hill. 

At point , the car has only gravitational potential energy 

At point , the car does not have any energy until it begins to move 

At point , the car has only kinetic energy 

The magnitude of the tension force in the string is the same in both cases. 

The work done on the block by the tension force is the same in both cases. 

The pin moves to the right at the same speed the bowling ball was initially travelling 

The bowling ball slows down and the pin moves to the right 

The bowling ball will change direction and begin moving to the left 

The pin stops the bowling ball from moving

The airbag does not change the force acting on the person

The force is decreased because the initial velocity is reduced by the airbag

The larger the airbag is, the greater the force acting on the person
