On the blank provided before each number, write A if the statement is true and the second statement is False; B if the statement is false and the second statement is true; C if both statements are true and D if both statements are false.
_____1. The rate of change in the position of an object and it's direction over a period of time is known as the objects speed.
The change in the displacement of an object after a specified time is the objects velocity.
_____2. A bicycle with an initial velocity of 2 m/s and an acceleration of 0.1 m/s² for 30 seconds will have a final velocity of 6 m/s.
Given an initial velocity of --2.0 m/s and an acceleration of – 6 m/s², it will take 0.5 s for a stone from a slingshot to have a displacement of 2m west.
____3. It is possible for a body to have an equal magnitude of distance and displacement.
A body moving in a circular path has the same magnitude of distance and displacement.
____4. When a ball is thrown vertically and it reaches it's maximum height, it's instantaneous velocity is zero.
The acceleration of a ball at the maximum height is -9.8 m/s².
____5. A particle moving to the east and speeding up has an eastward direction of acceleration.
A particle's direction of acceleration is alaways the same as the direction of the particle's motion.
_____6. The SI unit for velocity is m/s.
The SI unit for acceleration is meter (m).
_____7. A ball rolls down an inclined plane. The distance travelled by the ball is the same as the displacement of the ball from the top position to the ground.
Distance is defined as the total path length traveled by an object.
_____8. Three balls of different masses are dropped from the windows of a tall building. Ignoring the effect of Air resistance, all three balls will have the same free fall acceleration.
The ball with a greater mass will reach the ground first.
____9. An object moving with uniform acceleration is also moving with constant velocity.
Uniform motion states that a body is moving with constant motion.
____10. The slope of a velocity-time graph is the objects acceleration.
The acceleration of a body is the rate at which the velocity changes.
