What is Newton's Second Law of Motion?
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
An object in motion stays in motion unless acted upon by an external force.
The force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
For every action, there is an equal and opposite reaction.
What is the difference between mass and weight?
Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
Mass and weight are the same; both refer to the quantity of matter in an object.
Weight is the amount of matter in an object, while mass is the force exerted by gravity on that matter.
Mass is a measure of an object's volume, while weight is a measure of its density.
If a 10 kg object accelerates at 15 m/s², what is the force applied?
100 Newtons
150 Newtons
200 Newtons
250 Newtons
What is the unit of force in the International System of Units (SI)?
Joule (J)
Pascal (Pa)
Newton (N)
Watt (W)
What happens to acceleration if force increases while mass remains constant?
Acceleration decreases.
Acceleration remains constant.
Acceleration increases.
Acceleration becomes zero.
What is the formula for calculating acceleration?
a = F/m
a = m/F
a = F*m
a = F+m
What two variables define force?
Mass and acceleration.
Velocity and time.
Distance and speed.
Energy and momentum.
What is inertia?
The force that causes an object to move in a circular path.
The tendency of an object to resist changes in its state of motion.
The speed at which an object travels in a vacuum.
The gravitational pull exerted by an object on another object.
How does friction affect the motion of an object?
Friction increases the speed of an object.
Friction has no effect on the motion of an object.
Friction opposes the motion of an object, requiring more force to achieve acceleration.
Friction only affects objects at rest.
What is the effect of applying a force to an object at rest?
It will cause the object to accelerate in the direction of the force.
It will cause the object to remain at rest indefinitely.
It will cause the object to change its color.
It will cause the object to vibrate without moving.
How much force is needed to accelerate a 3 kg skateboard at 5 m/s²?
10 Newtons
15 Newtons
20 Newtons
25 Newtons
How do you calculate force?
F = ma, where F is force, m is mass, and a is acceleration.
F = mv^2, where F is force, m is mass, and v is velocity.
F = m/a, where F is force, m is mass, and a is acceleration.
F = m + a, where F is force, m is mass, and a is acceleration.
What is the relationship between mass and force in Newton's Second Law?
The greater the mass of an object, the more force is required to accelerate it.
Mass and force are unrelated concepts in physics.
Increasing mass decreases the required force for acceleration.
Force is independent of mass in Newton's Second Law.
If I apply the same force to a ping pong ball and a bowling ball, which one will accelerate faster?
The bowling ball.
The ping pong ball.
Both will accelerate at the same rate.
The ping pong ball will accelerate slower.
What happens to acceleration if mass increases while force remains constant?
Acceleration increases.
Acceleration remains the same.
Acceleration decreases.
Acceleration becomes zero.
