If an object is already moving, forces can make it speed up, slow down, or change direction.
Balanced forces do not cause a change in motion.
When one object pushes or pulls another object, the second object is exerting a force on the first object
Force and mass both affect the amount of change in an object's motion.
Magnetism is a contact force because magnets make contact.
Gravity only acts on heavy objects.
Friction is a type of contact force.
Every force has a magnitude and direction.
The strength of a force is measured in
To calculate net force the difference in Newtons between the two forces.
Objects that have alike charges
When you ride a roller coaster makes your body rise out of its seat at the top of the hill.
Force= x
The rate at which the speed or the direction of motion of an object changes over time.
Motion where the speed and direction do not change.
A car runs out of gas while moving forward on a flat, straight road. The car keeps rolling for a while because
This Newton's law states that when one object exerts a force on a second object, the second object exerts a force on the first.
Which of the following is a contact force?
Newton’s law of motion says that an object will stay in uniform motion unless a net force acts on the object.
Which of the following is NOT an example of accelerated motion?
A ball is rolled across four different surfaces with the same force. Which surface will slow the movement of the ball the most?
Name an example of a push force.
You are building a wooden car to enter in a downhill race. What can you do to make the car go as fast as possible? Please use complete sentences.
Describe a contact force and non-contact force that affect the motion of a baseball after a pitcher has thrown the ball. Use sentences.
