PHYSICS KINEMATICS QUESTIONS AND ANSWERS 2025/2026

When you drive a car and take a quick look on the speedometer, what do you see velocity or speed? - ANSWERSpeed. A ball is thrown vertically up and is caught at the starting point; compare the traveled distance and displacement of the ball. - ANSWERDisplacement is zero, while distance is 2h If the speedometer of a car reads constant speed 50 mi/h, does it mean that the car has constant velocity? - ANSWERYes. Can an object with a constant acceleration reverse it direction of travel? Explain. - ANSWERYes, an initial velocity in one direction with the acceleration in the opposite direction, causing it to reverse the direction Can an object have a varying velocity when its speed is constant? Explain. - ANSWERNo, the varying velocity means that the object has a nonzero acceleration, therefore causing a non constant speed What does the area under the curve on a velocity-versus-time graph represent? - ANSWERDisplacement. What does the slope of the curve on a displacement-versus-time graph represent? - ANSWERVelocity. What does the slope of the curve on a velocity-versus-time-time graph represent? - ANSWERAcceleration. Is it possible for an object to have average velocity equal to its instantaneous velocity? - ANSWERYes. What quantity describes how quickly you change your speed? - ANSWERAcceleration. Can an object have a southward velocity and a northward acceleration? - ANSWERYes. Is it possible for an object to have average speed equal to the magnitude of its average velocity? - ANSWERYes.
