SPH4U Sample Test - Kinematics
True/False
Indicate whether the sentence or statement is true or false.
____ 1. The slopes of position-time, velocity-time, and acceleration-time graphs represent velocity,
acceleration, and displacement, respectively.
____ 2. Two siblings leave their house and walk to the same school taking different routes. One of the
routes is farther, but the siblings take the same time to reach the school. It can be said that the two
siblings have the same average velocity but different average speeds.
____3. A car drives with constant speed around a corner. If it enters the corner travelling west and
leaves travelling south, its acceleration through the turn is directed south-west.
____ 4. An object is thrown vertically upward. At the top of its flight, when its velocity is momentarily
zero, its acceleration is zero.
____ 5. If air resistance is negligible, the acceleration of all projectiles is exactly the same.
____ 6. To achieve maximum range across a horizontal surface, the angle at which a projectile must be
launched is 90°.
____ 7. Provided that a boat always points perpendicular to the current in a river, the time it takes the
boat to cross is independent of the strength of the current.
