Action: your foot against the ball. Reaction: the ball against your foot. Both forces have the same magnitude, in accord With Newton’s third law.

A hammer hits a nail, driving the nail downwards into a piece of wood. The “reaction” is the force of the nail pushing upwards on the hammer, which stops the hammer. You are standing on the floor. The floor is pushing up on you (holding you up against gravity).

Newton’s third law of motion tells us that for every action force there is an opposed and equal reaction force. In any interaction between two objects, the first object exerts a force on the second, and the second object exerts a force back on the first object that is equal in magnitude and opposite in direction.

The force the ball exerts after being on by the bat produces the force on the players glove. The strong man can withstand the tension force exerted by the two horses pulling in opposite directions. How would the tension compare if only one horse pulled and the left rope were tied to a tree?

Is it true that when you drop from a branch to the ground below, you pull upward on Earth? If so, then why is the acceleration of Earth not noticed? Yes, it’s true. The Earth can’t pull you downward without you simultaneously pulling Earth upward.

Tangential acceleration occurs when the object changes its speed around the path. Explain what makes a passenger in a turning car slide toward the door of the car. When the car turns, the inertia of the passenger keeps the passenger moving in the same direction that the car was initially moving.

A major difference between tangential acceleration and centripetal acceleration is their direction. Centripetal means “center seeking”. Centripetal acceleration is always directed inward. Tangential acceleration results from the change in magnitude of the tangential velocity of an object.

Why are the passengers thrown outwards when a car in which they are travelling suddenly takes a circular turn? This is because of inertia of direction of the passengers They tend to maintain their direction of motion while the direction of car changes on turning .

Newton’s second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration. Created by Sal Khan.

Seat belts stop you tumbling around inside the car if there is a collision. Upon sensing a collision the seat belts lock in place. When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton’s First Law). The person moves against the seat belt, exerting a force on it.

What will happen if you’re in a car, and the driver slams on the brake? You will stop moving.

of inertia of motion

Acceleration and force are vectors. An object at rest tends to stay at rest and an object in motion tends to stay in motion in a straight line at a steady speed until an unbalanced force acts upon it. First Law. Imagine a ball moving in a straight line directly toward when another ball collides with it.

Generally yes. If you hit them in the side as they come into your lane you would have a shot at saying it was their fault, but if you hit squarely in the rear it is your fault. Yes, however, when they look at the damage to both vehicles, it can sometimes show how the accident happened, and who’s to blame.

A brake test, also known as a brake check, occurs when a driver deliberately brakes hard in front of another driver who is tailgating, or immediately after overtaking, causing the second driver to swerve or otherwise react quickly to avoid an accident.

If you suddenly hit the brakes after driving at a high rate of speed, it creates stress on the suspension and creates excess heat. If your brakes overheat, the pads will deteriorate faster and warp the rotors.

Brake checking is an illegal action. The person in front of you, in a brake checking situation, suddenly slams on their brakes. They do this to surprise you, and sometimes it’s to intentionally cause a collision. Regardless of where you are, this action puts you and others in danger.
