Forces and motion second Quizizz

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
