• ...average speed.

The gradient of a displacement-time graph represents the...

• ...speed.

• ...acceleration.

• ...velocity.

• ...distance travelled.

An airplane accelerates down a runway at 3.20 m/s² for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.

Which equation is appropriate?

• v_f=v_i+at

• Δx=v_it+1/2at²

• v_f²=v_i²+2aΔX

• Δx=((v_f+v_i)/2)t

This is a velocity-time graph.  What is the object doing in segment A?

• Positive acceleration
• Negative acceleration
• Constant Velocity
• Not moving

During which interval is the object not moving?

• B to C
• C to D
• D to E
• only at point A

The motion of an object is represented by the following velocity-time graph. The acceleration is greatest from ______

• A to B

• C to D

• D to E

• E to F
