IGCSE Motion Ch1-2

What is your physics teacher's name?

Speed=

• Distance / Time

• Distance x Time

• Velocity / Time

• Velocity x Time

What is the shape of a distance-time graph when the object is at rest?

• a horizontal line

• a vertical line

• a curve line

• a point

What is the distance travelled for motion with constant acceleration in a speed-time graph?

• the area under the graph

• the gradient of the graph

• the area under the horizontal line

• the gradient of the horizontal line

Weight is a _____________ force

What is the difference between the speed and velocity?

• Speed is a vector, Velocity is a scaler

• Speed is a scaler, Velocity is a vector

• Speed has the direction, while velocity does't

• Speed has unit while velocity doesn't

Acceleration =

• Change in velocity per unit of time

• Change in distance per unit of time

• Change in displacement per unit of time

• Velocity per unit of time

Speed ( on a distance-time graph) is _______

• The area under the graph

• The gradient of the graph

• The difference between the maximum and minimum of the graph

• negative gradient

Acceleration ( on a speed-time graph) =

• the area under the graph

• the line on the graph

• the gradient

• the curve line on the graph

On a speed-time graph, a straight line with a positive gradient means ___________

• Changing acceleration

• Stationary

• Constant speed

• Constant acceleration
