What causes objects to fall toward the ground, Friction, Gravity, Air resistance, Magnetic force, What does time measure in motion?, The distance an object travels, The duration over which motion occurs occurs, The change in an object's speed, The force acting on an object, 3. Which of the following is an example of acceleration?, A car moving at a constant speed of 60 km/h, a parked bicycle, a bus increasing its speed from 40 km/h to 60 km/h, a person sitting on a bench, 4. A car is moving at 20 m/s and slows down to 10 m/s in 5 seconds. What type of acceleration is this?, Positive acceleration, Negative acceleration (deceleration), Uniform motion, Free fall, 5. What happens when an object experiences uniform acceleration?, Its velocity stays the same., Its velocity increases or decreases by equal amounts in equal time intervals., It moves at a constant speed., It comes to a stop immediately., 6. Which of the following is an example of negative acceleration, A soccer ball rolling down a hill, A car slowing down at a traffic light, A runner sprinting faster at the finish line, A rocket launching into space, 7. What happens to the velocity of an object in free fall if we ignore air resistance?, It remains constant., It decreases over time., It increases at a constant rate., It stops moving after a while., 8. What happens to an object's speed when it experiences positive acceleration?, It stays the same, it decreases, it increases, it moves backward, 9. If an object has zero acceleration, what does that mean?, The object is moving at a constant velocity., The object is speeding up., The object is slowing down., The object is falling due to gravity., 10. A car starts from rest and accelerates at 3 m/s². What will happen to the car’s velocity?, It will stay the same over time., It will increase by 3 m/s every second., It will increase by 6 m/s every second., It will decrease by 3 m/s every second..
