Accelerated Motion

• 2.5 m

• 3.0 m

• 20 m

• 28 m

which feature of a graph allows acceleration to be determined

• the area under a displacement-time graph

• the area under a velocity-time graph

• the slope of a displacement-time graph

• the slope of a velocity time graph

A particle is moving in a straight line with uniform acceleration.

which graph represents the motion of the particle?

• A

• B

• C

• D

deducing the acceleration = deduce the gradient of velocity-time graphs

• True

• False

The acceleration or the 'g' will be ...... since the direction of motion is same as the direction acceleration of gravity.

If I drop an apple from the top of building, and it takes 5s to hit the ground calculate how tall the building is in meters if the acceleration of gravity is 9.81 m.s-2? (write in 2 dp)

• 122.63 m

• 122.64 m

• 122.62 m

• 122.65 m

Andi drops a rock from rest from a guard rail overlooking a valley. What is the velocity of the rock at 11s? the acceleration of gravity is 9.81 m.s^-2

One of the question of motion may be written as

v = u + a.t

Name the quantity represented by the symbol u

Use data from fig 3.1 to determine the distance travelled by the ball during the first 0.40

Suppose a tourist threw the rock with an initial velocity of 8.0 m/s (down). Determine the velocity at 4s. The acceleration of gravity is 9.81 m/s
