A mug of tea (T_m) is at rest on a table. Select the correct pairing of forces.

Gravitational force pulls (T_m) towards the table. (T_m) pushes on the table in the opposite direction.

(T_m) pushes on the table. The table pushes back on (T_m) in the opposite direction.

(T_m) pulls the table towards it with gravitational force. The table pushes back on (T_m) in the opposite direction.

(T_m) pushes on the table. The table is pulled down by gravitational force.

Select the best statement for Newton's 1st Law:

An object will remain at rest unless acted on by a resultant force.

An object will remain at rest or at a constant velocity unless acted on by a resultant force.

The rate of change in momentum of a body is directly proportional to the resultant force applied.

When two objects interact they will exert equal and opposite forces on each other.

Select the missing phrase. "A joiner uses a hammer to hit a nail into wood. When the hammer strikes the nail, _____________

the nail exerts an equal force back on the hammer and doesn't move.

the nail exerts an equal force back on the hammer and moves into the wood.

the nail exerts a force proportional to its size back on the hammer and doesn't move.

the nail exerts a force proportional to its size back on the hammer and moves into the wood.

Select the best statement for Newton's 3rd Law:

An object will remain at rest or at a constant velocity unless acted on by a resultant force.

An object will remain at rest unless acted on by a resultant force.

When two objects interact they will exert equal and opposite forces on each other.

The rate of change in momentum of a body is directly proportional to the resultant force applied.

Lauren Steadman set off on her run as part of the paratriathlon at Rio Olympics. Select the best description for her motion.

Her leading foot exerts a force down on the road, so the road exerts an equal and opposite force upwards.

As she places her leading foot down and pushes up at an angle, a gravitational force pulls her back to earth at the same angle moving her forward.

Her leading foot exerts a force forwards to the road. The road exerts an equal and opposite frictional force backwards.

Her leading foot exerts a force backwards to the road. The road exerts an equal and opposite frictional force forward.

Select the best statement for Newton's 2nd Law

An object will remain at rest or at a constant velocity unless acted on by a resultant force.

The rate of change in momentum of a body is directly proportional to the resultant force applied.

An object will remain at rest unless acted on by a resultant force.

When two objects interact they will exert equal and opposite forces on each other.
