Science Flash Cards
What’s and example of newtons second law of motion F=ma?
Riding your bicycle, racing cars,kicking the ball and two people walking.
What is force?
Force is the push or pull on an object with mass causes it to change its velocity.
How does an elastic material exert elastic force?
As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction.
What are some examples of elastic forces?
Some examples are hair scrunchies, elastic waistband, rubber band and a resistance band.
What is elasticity?
Elasticity is the ability of an object to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
How do Newton’s laws apply to everyday life?
A ball rolling on a flat surface will keep on running unless an outside force stops it. A car moving down the highway will remain in motion unless some external force changes its speed.
What’s an example of Newstons third law of motion?
An example would be a bouncing ball, when a ball hits the ground, the ball applies an action force on the ground. The ground applies a reaction force and the ball bounces back.
What’s an example of Newton’s first law of motion?
