Newton's first law of motion is also known as the law of:
Gravity
Inertia
Acceleration
Action-Reaction
Newton's second law of motion is also known as the law of:
Inertia
Mass and acceleration
Action and reaction
Gravitation
Newton's third law of motion is also known as the law of action and reaction. What does it state?
For every action, there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an external force.
Force equals mass times acceleration.
Energy cannot be created or destroyed.
Another name for the first law of motion is the law of (a) .
Newton's first law applies when you kick a football on a football field. What does this law state?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
For every action, there is an equal and opposite reaction.
Force equals mass times acceleration.
Energy cannot be created or destroyed.
If you kicked a ball in space, according to Newton's first law, what would happen?
The ball would stop immediately.
The ball would continue moving in the same direction at a constant speed.
The ball would change direction randomly.
The ball would fall back to the kicker.
Newton's first law explains the need for seatbelts and airbags in cars because:
They provide comfort during driving.
They help maintain the car's speed.
They protect passengers by counteracting inertia.
They enhance the car's fuel efficiency.
What does Newton's second law of motion state about acceleration?
It is produced when a balanced force acts on an object.
It is produced when an unbalanced force acts on an object.
It is not related to force.
It is constant regardless of force.
According to Newton's second law, if you use the same force to push a lorry and a car, which one will have a greater acceleration?
Lorry
Car
Both will have the same acceleration
None of the above
It is easier to push an empty shopping trolley than a full one because:
an empty trolley has less mass and requires less force to move.
a full trolley has more mass and requires less force to move.
an empty trolley has more friction with the ground.
a full trolley has less friction with the ground.
What is the approximate value of acceleration due to gravity, g?
If F = 20N, and a = 5m/s² what is the mass (m) in kg?
2 kg
4 kg
5 kg
10 kg
Explain how Newton's third law is demonstrated when air rushes out of a balloon.
The balloon moves in the opposite direction to the air rushing out.
The balloon remains stationary.
The balloon moves in the same direction as the air rushing out.
The balloon explodes.
What is a reaction force?
A force that acts in the same direction as an applied force.
A force that acts in the opposite direction to an applied force.
A force that acts perpendicular to an applied force.
A force that acts in random directions.
What happens to an object in motion?
A) It will stop immediately.
B) It will continue with constant speed and direction unless acted on by an unbalanced force.
C) It will change direction randomly.
