Total questions: 10
Worksheet time: 5mins
What is the definition of motion in physics?
Motion is the speed of an object at rest.
Motion refers to the force applied to an object.
Motion is the change in position of an object over time.
Motion is the energy possessed by a moving object.
State Newton's First Law of Motion.
An object will remain in motion until it collides with another object.
An object will accelerate unless a force is applied.
An object will remain at rest or in uniform motion unless acted upon by an external force.
An object will change its velocity only if it is in motion.
What is the formula for calculating force?
F = m - a
F = m / a
F = m + a
F = m * a
Explain the concept of inertia.
Inertia is the resistance of an object to any change in its motion.
Inertia is the energy stored in a moving object.
Inertia is the force that causes an object to move faster.
Inertia is the speed of an object in motion.
How does mass affect the acceleration of an object?
Mass has no effect on acceleration.
Greater mass always increases acceleration.
Mass affects acceleration inversely; greater mass results in lower acceleration for a given force.
Acceleration is independent of mass.
What is the relationship between action and reaction according to Newton's Third Law?
Action and reaction are unrelated forces.
Only actions have consequences, not reactions.
For every action, there is an equal and opposite reaction.
Reactions can occur without an action.
Give an example of an object in uniform motion.
A car moving at a constant speed on a straight road.
A person walking in a crowded area.
A train coming to a stop at a station.
A bicycle accelerating down a hill.
What is the difference between speed and velocity?
Speed is always greater than velocity.
Velocity measures distance only, not direction.
Speed can be negative while velocity cannot.
Speed is scalar; velocity is vector (includes direction).
How does friction affect motion?
Friction only affects stationary objects.
Friction has no effect on motion.
Friction increases the speed of moving objects.
Friction opposes motion, slowing down or stopping moving objects.
Describe a real-life application of Newton's Second Law.
Using a slingshot to launch projectiles at a target.
Car safety mechanisms, such as seatbelts, applying force to prevent injury during sudden stops.
Calculating the weight of an object on different planets.
Designing a roller coaster to maximize thrill without safety measures.
