Section 1 - Motion

What do you need for friction?

• Air

• A surface to slide on

• Nothing!

• Sunlight

What is the equation for speed?

• speed = time / distance
• speed = distance / time
• speed = distance x time

• speed = distance - time

A tractor is travelling 100m down a road and it takes 2s to get the end. What is the speed of the car?

• 25 m/s
• 75 m/s
• 40 m/s
• 50 m/s

What is speed measured in?

• kilograms
• meters per second

• degrees
• meters

Which section of this distance time graph is the object stationary (staying still)?

• The object is stationary when the distance-time graph shows a curve
• The object is stationary when the distance-time graph is a diagonal line
• The object is stationary when the distance-time graph has multiple peaks
• The object is stationary (staying still) when the distance-time graph shows a horizontal line (flat line) at a certain distance.

Which section of this distance time graph is the object moving backwards?

• The section with a horizontal line.
• The section with an upwards slope.

• The section with a downwards slope.

What is the difference between speed and velocity?

• Speed is scalar, velocity is vector.

• Speed is a force, velocity is a distance.
• Speed and velocity are the same thing.
• Speed is a vector, velocity is scalar.

What is the equation for acceleration?

• a = Δv - t

• a = Δv / t

• a = Δv + t

• a = Δv x t

What are the units for acceleration?

• m/s
• m/s^2
• km/h^2
• cm/s^2

What is Newton's 2nd Law?

• Force = Mass x Acceleration
• Mass = Acceleration / Force
• Acceleration = Force / Mass
• Mass = Force / Acceleration
