'The box moved 5m to the right' is an example of...?

• Distance

• Displacement

• Speed

• Velocity

What does the formula V= d/t calculate?

• Average speed

• Distance

• Displacement

• Acceleration

Which of the following is NOT true about velocity?

• Measures in the change of an object's position

• A direction must be stated

• Is a vector

• Measures the rate at which a distance is covered

what does the formula a=∆v/t measure?

• Speed

• acceleration

• deceleration

• distance travelled

This distance/ time graph shows a cars motion. What is the car doing?

• Staying still

• Accelerating

• Decelerating

• Moving backwards

What is a 'Normal' force?

• A force which acts upon an object as it travels through the air.

• A force applied to an object by another object usually through pushing

• A supporting force which occurs when one object is in contact with another stable object

• A force exerted by a surface as an object moves across it.

What does 'inertia' mean?

• The thing that makes an object resist a change in motion

• An object is at rest

• The unbalanced force which acts upon an object

• The balance of forces by things like gravity

Which object has the most inertia?

• A brick

• A dinosaur

• The moon

• A pebble

What two factors do I need to know to work out the net force of an object?

• Distance and time

• Mass and acceleration

• Volume and mass

• Acceleration and distance

An object will remain at rest unless...

• Too much time has passed

• Acted upon by an outside, unbalanced force

• Acted upon by a new force from within the object

• An opposite force appears
