Which of the following is Stated by Newton’s first law of motion?
Force equal acceleration times mass
As the mass of the object increases, the acceleration decreases
An object will remain in its state whether stationary or constant speed unless acted by unbalanced force
For every action force, there is a reaction force.
Which of the following is Stated by Newton’s second law of motion?
For every action force, there is a reaction force
Force usually exists as pairs
Force is directly proportional to mass and inversely proportional to acceleration
Acceleration is inversely proportional to mass and directly proportional to force
What is inertia?
When the net force on an object is unbalanced
The tendency of an object to remain stationary or moving at the same speed
When unbalanced forces on an object cause it to accelerate
When there is a reaction force for every action force
Newton’s first law is called ........
Law of force, mass and acceleration
Action and reaction forces
Force pairs law
Law of inertia
Which of the following actions can be explained by Newton’s first law of motion?
Why it is easier to pull a 10 kg cart than 100 kg cart
Why a rocket stays at rest until the engine fires.
How the wall applies force on the pen when the pen touches it.
Why an equal force will cause smaller mass object to accelerate more
Which of the following actions can be explained by Newton’s first law of motion?
why is it easier to pull 10 kg shopping cart than 100 kg
How acceleration is inverse proportional to mass
What can make a ball change speed and direction
How reaction forces are equal to action forces in magnitude and opposite in direction
Which of the following actions can be explained by Newton’s second law of motion?
How the same force is needed to push 10 kg and 100 kg carts with the same acceleration
How force is direct proportional to acceleration and mass
How acceleration is direct proportional to mass and inverse proportional to force
How A rockets start launching when unbalanced forces act on it
Which of the following actions can be explained by Newton’s second law of motion?
The acceleration is directly proportional to force and inverse proportional to mass
More force is needed to push a 100 kg car than 10 kg cart
If the same force is applied to 10 kg and 100 kg carts, the 10 kg cart will accelerate more than 100 kg cart
All the choices are correct
What makes a rocket stays in its place?
Due to inertia
Due to balanced forces acting on it.
Because the net force on it is equal zero
All the choices are correct
...... is the property that makes the object resist Change in motion
Net force
Unbalanced force
Inertia
Force pairs
According to Newton’s first law of motion, What will happen to a rocket?
The rocket will stay in its place as long as all the forces are balanced
In order to launch the rocket, the engine has to create great force that exceeds the gravity so it moves up
When the rocket is launched, the forces are unbalanced so the net force is-not equal zero
All the choices are correct
According to Newton’s first law, what happens to a bowling ball?
When you push the ball, it accelerates in the beginning due to the unbalanced force due to the push from your hand.
The ball moves after a while at a constant speed forever if we neglect the friction force as in space
The ball will slow down and eventually stop after hitting the other balls
All the choices are correct
According to Newton’s first law of motion, a ball moving at a constant speed will continue moving at a constant speed forever if that ball didn’t hit anything and if we remove friction force
True
False
If we throw a ball away in space and away from gravity, What will happen to the ball?
It will move at a constant speed in a straight line
It will speed up gradually
It will slow down gradually
It will accelerate and change directions
Acceleration is ......
Direct proportional to force
Inverse proportional to mass
Rate of change in velocity
All the choices are correct
If the same force( 20 N) is applied to two carts: one 2 kg and the other is 5kg. Which one will accelerate more?
2 kg
5 kg
Both will accelerate the same
if the same force is applied to two objects: one 10 kg and the other 15 kg.
10 kg will accelerate more than 15 kg
True
False
Object A and Object B are dropped. The objects
A accelerates more. Which one has higher mass?
Object A
Object B
