A student investigates a wooden block sliding down a smooth inclined plane onto a smooth horizontal table, where it travels at a constant velocity.
Suggest the equipment the student uses to measure the distance the block slides down the inclined plane.
Suggest the equipment the student uses to measure the time it takes for the block to slide down the inclined plane.
Below is the velocity-time graph representing the motion of the block:
State the time at which the block starts to move.
State the time at which the block reaches the bottom of the inclined plane.
Describe how the acceleration of the block will change if the inclined plane is made steeper.
Describe how the line on the velocity-time graph representing the acceleration would change if the inclined plane is made steeper.
Velocity is a vector quantity, whereas speed is a scalar quantity.
Complete the sentence about scalar quantities. Use words from the list:
