Question

Pre-lab activity 1) What happens to an object's acceleration if the object's mass is kept constant while the applied force varies? Explain. 2) If you ask most people what force makes a car accelerate forward, they will say "the force of the engine." But what force is DIRECTLY responsible for making the car accelerate? Explain. 3) A car is driven up a steep hill at constant speed. Discuss all the forces acting on the car. What pushes it uphill? Explain. 4) State Newton's three laws of motion with specific example for each.

Explanation / Answer

(1) Acceleration vs applied force by keeping mass constant:

According to Newton's second law, it is expressed that applied force is equal to the product of mass and acceleration. i.e appleid force is directly proportional to the acceleration.

When mass is constant, the acceleration of an object varies linearly with respect to applied force.

i.e. Acceleration increases linearly when force increases and it decreases linearly when force decreases .
